FOOT-WARM ER.

SPECIFICATION forming part of Letters Patent No. 567,166, datedSeptember 8, 1896. Application filed May 23, 1895. Serial No. 550,397.(Nomodel.)

To all whom, it may concern:

Be it known that we, CLYDE A. RICKARD and JOHN A. LOWRIE, citizens ofthe United States, residing at Seville, in the county of Medina andState of Ohio, have invented a new and useful Foot-VVarmer, of which thefollowing is a specification.

This invention relates to that class of heaters principally designed forwarming the feet in vehicles, and which, with slight changes, areadapted for warming other parts of the body whenever required; and theobject of the invention is the provision of a heater of the characterdescribed whichwill be simple in construction, compact in arrangement,and consequently inexpensive.

With this and other objects in view the improvement consists of thenovel features which hereinafter will be more fully set forth andclaimed, and which are illustrated in the accompanying drawings, inwhich- Figure l is a rear elevation of the heater. Fig. 2 is a plansection on the line X X of Fig. l. Fig. 3 is a vertical section on theline Y Y of Fig. 2.

The heater is preferably rectangular in shape, and comprises a shallowbox or casing, whose top l slopes gradually from front to rear forconvenience and comfort in supporting` the feet. The sides 2 extendparallel and are connected at their ends to the front 3 and back 4,respectively, and at their top and bottom edges to the' top l and bottom5, whereby a substantial structure is obtained. This box or casing ispreferably formed of sheet metal, so as to resist the action of the heatand prevent fire. The front 3 is provided near its lower edge with aseries of draft-inlets G, by means of which a sufficient quantity of airis admitted within the box or casing to support combustion of the fuel.The back/l has a correspon ding series of openings 7 along its upperedge for the escape of the heated air, and by means of which acirculation of pure air is obtained through the box or casing, and theseopenings 7 are controlled by a sliding damper 8, by means of which thedraft is regulated and the consequent consumption of fuel controlled.This damper 8 is a metal plate, having a series of openings 9 tocorrespond in position, size, and number with the openings 7, so as toregister therewith, and by sliding the said plate or damper to one sideor the other the openings 7 and 9 are brought more or less out ofregister, or entirely closed, as desired, whereby the proper consumptionof the fuel can be accomplished. The rear edge portions of the top 1 andthe bottom 5 extend beyond the outwardly-flanged edges of the back 4E,and are bent thereover to hold the parts in xed relation, and arerecurved, as shown at 10, to form ways to receive the iianged edges 11of the plate or damper 3, to hold the latter in proper relation andguide it in its movements. By this means a substantial joint is hadbetween the back, top, and bottom, and a simple and inexpensive means is.provided to guide the damper in its movements and hold it in place, thesaid damper operating between the ianged edges of the back and held inplace by the recurved edges of the top and b ottoni.

One or more iire-boxes l2 are placed within the box or casing, andconsist of tubes of reticulated or perforated metal, and may havepermanent attachment with the heater or be removably connectedtherewith', as desired and as shown in Figs. 2 and 3. These tubularlire-boxes have permanent attachment with the back 4. and open at theirouter ends through the said back for the admission of fuel therein, saidopenings 13 being closed by the plate or damper S.

The fuel designed to be used in the heater is a carbon stick of specialmanufacture, and which when ignited will burn slowly and give offsuflicient heat to attain the desired result. The fuel after beingignited is placed within the tubular fire-box through the opening 13,the damper 8 being slid to one side so as to disclose the said opening,and after the fuel is in position the damper is moved, so as to closethe opening 13 and retain the fuel in place within the tubular lire-box.

It will be seen that the air enters the openings 6 in the front of thebox or casing, passes within the latter, reaches the fuel through theopenings or perforations in the sides of the fire-boxes, and escapesthrough the openings 7 in the back 4, and by controlling said IOOopenings 7 by a proper adjustment of the It will be understood that theheater can be constructed and provided in diiferent styles and shapes,according to the required need. Therefore it will be seen that in theembodiment of the invention various changes in the tom projecting beyondand bent over the outer flanges of the back and recurved, forinj ingguideways, and having air-openings in 1 its front and back, a dampercomprising a plate having its edge portions outwardly iianged to operatein the said guideways, and between the iianged edges of the said backand having openings to correspond in position and number with theopenings in the i substantially in the manner and for the purback of thecasing, and a tubular fire-box having perforated sides located withinthe easing and projecting across the path of the air-currentstherethrough, substantially as described for the purpose set forth.

2. A heater for the purposes specified, comprising a casing havingopenings in its sides for the passage of the air therethrough, a tubularfire-box located within the casing and having its outer end openingthrough a side thereof having air-openings, and a damper 35 slidablymounted against the side of thecasing supporting the fire-box to closeits open end and to regulate the draft-openings, substantially as setforth.

3. The herein-specified heater, comprising a casing having the top andbottom edges of its back outwardly iianged, and having the rear edgeportions of its top and bottom projecting beyond and bent over the outeriianges of the back and recurved, forming 45 guideways, and havingair-openings in its front and back, tubular fire-boxes located withinthe casing and having connection with the back and opening therethrough,and a damper comprising a plate having its edge portions outwardlyflanged to operate in the guideways formed by the recurved edge portionsof the top and bottom and between the flanged edges of the said back,and having openings to correspond in position and number with thedraft-openings in the said back, and adapted to close the open ends ofthe re boxes and to regulate the draftopenings,

pose specified.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
